Thermal Engineer

Join a cutting-edge aerospace engineering team supporting next-generation space systems for a critical U.S. space program. This opportunity is ideal for an experienced Thermal Engineer who is passionate about spacecraft development, thermal analysis, and solving complex engineering challenges in a highly collaborative, mission-driven environment.

In this role, you'll support the thermal design, analysis, and validation of spacecraft, precision electro-mechanical systems, cryogenic systems, antenna communications hardware, and other advanced aerospace technologies. You'll work alongside multidisciplinary engineering teams throughout the product lifecycle, from concept and design through testing and integration.
